Struct VectorClock 

pub struct VectorClock { /* private fields */ }

Vector clock for tracking causality in distributed systems.

Implementations

impl VectorClock

pub fn new() -> Self

Create a new vector clock.

pub fn increment(&mut self, node: &NodeId)

Increment the clock for a specific node.

pub fn get(&self, node: &NodeId) -> u64

Get the current value for a node.

pub fn merge(&mut self, other: &VectorClock)

Merge this clock with another (take maximum of each component).

pub fn happens_before(&self, other: &VectorClock) -> bool

Check if this clock happened before another.

pub fn is_concurrent(&self, other: &VectorClock) -> bool

Check if two clocks are concurrent (neither happened before the other).

Trait Implementations

impl Clone for VectorClock

fn clone(&self) -> VectorClock

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VectorClock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VectorClock

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VectorClock

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VectorClock

fn eq(&self, other: &VectorClock) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for VectorClock

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
